Miembros de placas intercaladas estructurales.Members of interspersed plates structural.
La presente invención se refiere a miembros de placas intercaladas estructurales que comprenden dos placas externas y un núcleo de plástico o material polimérico unido a las placas externas con una resistencia suficiente para contribuir sustancialmente a la resistencia estructural del miembro.The present invention relates to members of structural interleaved plates comprising two plates external and a core of plastic or polymeric material attached to the external plates with sufficient strength to contribute substantially to the structural strength of the member.
Los miembros de placas intercaladas estructurales se describen en los documentos US 5.778.813 y US 6.050.208 y comprenden placas de metal externas, por ejemplo de acero, unidas juntas con un núcleo de elastómero intermedio, por ejemplo, de poliuretano no espumado. Estos sistemas de placas intercaladas pueden usarse en muchas formas de construcción para sustituir a las placas de acero reforzadas y simplificar en gran medida las estructuras resultantes, mejorando la resistencia y el rendimiento estructural (rigidez, características de amortiguación) mientras que ahorran peso. Otros desarrollos de estos miembros de placas intercaladas estructurales se describen en los documentos WO 01/32414 y US 2001/0035256 A. Como se describe en ellos, las formas de espuma pueden incorporarse en la capa de núcleo para reducir el peso y pueden añadirse placas de rotura metálicas transversales para mejorar la rigidez.The interspersed plate members Structural are described in US 5,777,813 and US 6,050,208 and comprise external metal plates, for example of steel, joined together with an intermediate elastomer core, by example, of non-foamed polyurethane. These plate systems interleaved can be used in many forms of construction to replace reinforced steel plates and simplify greatly measure the resulting structures, improving strength and structural performance (stiffness, damping characteristics) while saving weight. Other developments of these members of structural interleaved plates are described in WO documents 01/32414 and US 2001/0035256 A. As described in them, the forms foam can be incorporated into the core layer to reduce the weight and transverse metal break plates can be added to improve stiffness.
De acuerdo con los contenidos del documento WO 01/32414 las formas de espuma pueden ser huecas o macizas. Las formas huecas generan una mayor reducción de peso y, por lo tanto, son ventajosas. Las formas descritas en este documento no se limitan a hacerlas de material de espuma de peso ligero y pueden hacerse también de otros materiales, tal como cajas de madera o acero.According to the contents of the WO document 01/32414 foam shapes can be hollow or solid. The Hollow shapes generate greater weight reduction and, therefore, They are advantageous. The forms described in this document are not they just make them from lightweight foam material and can be also made of other materials, such as wooden boxes or steel.
La Solicitud de Patente Internacional WO 02/078948 es otro desarrollo del concepto de inclusión de formas huecas y describe formas que son fáciles de fabricar y montar, en particular se describen formas alargadas huecas hechas de piezas unidas a presión.WO International Patent Application 02/078948 is another development of the concept of inclusion of forms hollow and describes shapes that are easy to manufacture and assemble, in particular elongated hollow shapes made of parts are described attached to pressure.
Las formas básicas de los miembros de placas intercaladas estructurales descritas en los documentos US 5.778.813 y US 6.050.208 tienen propiedades de resistencia al fuego excelentes, de manera que los miembros de placa de las dimensiones adecuadas para propósitos de construcción de barcos superan fácilmente los ensayos de exposición a fuego A-60 de Seguridad para la Vida en el Mar (SOLAS) de la Organización Marítima Internacional (IMO), incluso sin un aislamiento adicional. Sin embargo, los miembros de placa tales como los descritos en los documentos WO 01/32414 y WO 02/078948 no superan estos ensayos sin un aislamiento adicional en el lado expuesto al fuego. Sin dicho aislamiento, la temperatura del lado no expuesto sube rápidamente.The basic forms of plate members structural interleaves described in US 5,777,813 and US 6,050,208 have fire resistance properties excellent, so that the plate members of the dimensions suitable for shipbuilding purposes exceed Easily test fire exposure A-60 of Safety for Life at Sea (SOLAS) of the Organization International Maritime (IMO), even without additional isolation. However, plaque members such as those described in the WO 01/32414 and WO 02/078948 do not pass these tests without additional insulation on the side exposed to fire. Without saying insulation, the temperature of the unexposed side rises quickly.
Un objetivo de la presente invención es proporcionar miembros de placas intercaladas estructurales que incluyen formas de peso ligero dentro del núcleo que tiene una resistencia a fuego mejorada y, preferiblemente, pueden satisfacer el ensayo de resistencia al fuego prescrito.An objective of the present invention is provide structural interleaved plate members that include lightweight forms inside the core that has a improved fire resistance and preferably can meet The prescribed fire resistance test.
De acuerdo con la presente invención, se proporciona: un miembro de placas intercaladas estructural y un método de preparación de dicho miembro como se define en las reivindicaciones adjuntas.In accordance with the present invention, provides: a member of structural interleaved plates and a method of preparing said member as defined in the attached claims.
Los presentes inventores han determinado que los miembros de placas intercaladas estructurales de la técnica anterior con formas de peso ligero hechas de espuma fallan en los ensayos de exposición a fuego por que la espuma se funde rápidamente dejando huecos relativamente grandes que se extienden entre las placas frontales del panel. Cuando la forma de peso ligero es hueca, los huecos existen desde el principio. El aire y otros gases en estos huecos pueden conducir entonces calor al panel en el lado alejado del fuego. Construyendo las formas de peso ligero de un material resistente al fuego, específicamente lana mineral, se evita esto. La forma no se funde y, por lo tanto, no hay un hueco abierto grande a través del cual el calor pueda conducirse por convección.The present inventors have determined that structural interleaved plate members of the technique anterior with lightweight shapes made of foam fail in the fire exposure tests because the foam melts quickly leaving relatively large gaps that extend between the front panels of the panel. When the weight form Light is hollow, the gaps exist from the beginning. Air and other gases in these holes can then heat the panel On the far side of the fire. Building weight forms lightweight of a fire resistant material, specifically wool mineral, this is avoided. The form does not melt and therefore does not there is a large open hole through which heat can conduct by convection.
Preferiblemente, la forma de peso ligero debería hacerse de un material que tenga un punto de ignición y un punto de fusión mayores de 1000ºC.Preferably, the lightweight form should be made of a material that has a flash point and a flash point melting greater than 1000 ° C.
En una realización preferida de la invención, la espuma de peso ligero comprende un material resistente al fuego encerrado en una barrera impermeable a la forma líquida de dichos plásticos o material polimérico.In a preferred embodiment of the invention, the Lightweight foam comprises a fire resistant material enclosed in a barrier impermeable to the liquid form of said Plastics or polymeric material.
Con esta disposición, el miembro de placa puede formarse por moldeo por inyección después de la colocación de las formas de peso ligero en una cavidad hecha mediante las dos placas externas, como se describe en los documentos WO 01/32414 y WO 02/078948. La barrera evita que los plásticos líquidos o el material polimérico empapen el material aislante. Por ejemplo, las formas de peso ligero pueden comprender un tipo preformado, hecho de plástico sólido, espuma, metal u otro material, en el que se coloca el material aislado. En este caso, la forma puede construirse como en cualquiera de las realizaciones descritas en el documento WO 02/078948. Como alternativa, el material aislante puede adaptarse a la geometría requerida y pulverizarse o sumergirse en un material de recubrimiento que se endurece para proporcionar la capa externa. Otra alternativa es enrollar el material aislante en una capa externa fina tal como una lámina metálica, fieltro o tela mineral.With this arrangement, the plate member can be formed by injection molding after placement of the Lightweight shapes in a cavity made using the two plates external, as described in WO 01/32414 and WO 02/078948. The barrier prevents liquid plastics or material polymer soak the insulating material. For example, the ways of Light weight can comprise a preformed type, made of plastic solid, foam, metal or other material, in which the insulated material In this case, the shape can be constructed as in any of the embodiments described in WO 02/078948. Alternatively, the insulating material can be adapted to the required geometry and be sprayed or immersed in a material coating that hardens to provide the outer layer. Another alternative is to roll the insulating material in a layer thin outer such as a metal sheet, felt or fabric mineral.
El material aislante es preferiblemente lana
mineral y puede tener una densidad en el intervalo de 30 kg/m^{3}
a
200 kg/m^{3}.The insulating material is preferably mineral wool and may have a density in the range of 30 kg / m3 at
200 kg / m 3.
Debe observarse que las formas de peso ligero sirven para reducir la masa del miembro de placas intercaladas estructural y no necesitan contribuir significativamente a su resistencia estructural. Los requisitos principales de las formas de peso ligero son que sean de una menor densidad que los plásticos o el material polimérico que forman núcleo y que tengan propiedades térmicas y mecánicas suficientes para mantener la forma deseada durante la inyección y curado del núcleo de plásticos o de polímero. La distribución de las formas dentro del núcleo puede ser como se describe en el documento WO 03/101728.It should be noted that light weight forms serve to reduce the mass of the interspersed plate member structural and do not need to contribute significantly to your structural strength The main requirements of the forms Lightweight are that they are of a lower density than plastics or the polymeric material that forms a nucleus and that have properties thermal and mechanical enough to maintain the desired shape during injection and curing of the core of plastics or polymer. The distribution of the forms within the nucleus can be as it is described in WO 03/101728.
Los materiales, dimensiones y propiedades generales de las placas externas del miembro de placas intercaladas estructural de la invención pueden elegirse como se desee según el uso particular que se vaya a dar al miembro de placas intercaladas estructural y, en general, puede ser como se describe en los documentos US-5.778.813 y US-6.050.208. Habitualmente se usa acero o acero inoxidable con un espesor de 0,5 a 20 mm y puede usarse aluminio cuando sea deseable un peso ligero. Análogamente, el núcleo de plásticos o de polímero puede ser de cualquier material adecuado, por ejemplo, un elastómero tal como poliuretano como se describe en los documentos US- 5.778.813 y US-6.050.208.The materials, dimensions and properties general of the outer plates of the interspersed plate member Structural of the invention can be chosen as desired according to the particular use to be given to the interspersed plate member structural and, in general, can be as described in the US-5,778,813 and US 6,050,208. Usually steel or steel is used stainless with a thickness of 0.5 to 20 mm and aluminum can be used when a light weight is desirable. Similarly, the core of Plastics or polymer can be of any suitable material, for example, an elastomer such as polyurethane as described in US-5,778,813 and US-6,050,208.
La presente invención se describirá a continuación con referencia a realizaciones ejemplares y los dibujos esquemáticos adjuntos, en los que:The present invention will be described in continued with reference to exemplary embodiments and drawings attached schematics, in which:

En los diversos dibujos, las partes similares se indican mediante números de referencia similares.In the various drawings, similar parts are indicated by similar reference numbers.
El miembro de placas intercaladas estructural mostrado en la Figura 1 comprende placas externas superior e inferior (placas frontales) 11, 12 que pueden ser de acero y que tienen un espesor, por ejemplo, en el intervalo de 0,5 a 20 mm. Las placas de borde se sueldan entre las placas frontales 11, 12 alrededor de sus periferias externas para formar una cavidad cerrada. En la cavidad entre las placas frontales 11, 12 hay un núcleo 13 de plásticos o material polimérico, preferiblemente un elastómero de poliuretano compacto (es decir, no espumado). Este núcleo puede tener un espesor en el intervalo de 15 a 200 mm; en la presente solicitud 160 mm es adecuado. El núcleo 13 se une a las placas frontales 11, 12 con suficiente resistencia y tiene propiedades mecánicas suficientes para transferir las fuerzas de cizalla esperadas durante el uso entre las dos placas frontales. La resistencia de enlace entre el núcleo 13 y las placas frontales 11, 12 debería ser mayor de 3 MPa, preferiblemente 6 MPa y el módulo de elasticidad del material de núcleo debería ser mayor de 250 MPa. Para aplicaciones de carga baja, tal como paneles de suelo, donde las cargas típicas de uso y ocupación son del orden de 1,4 kPa a 7,2 kPa, la resistencia de enlace puede ser menor, por ejemplo, aproximadamente 1 MPa. Gracias a la capa de núcleo, el miembro de placas intercaladas estructural tiene la resistencia y capacidad de soporte de carga de una placa de acero reforzado que tiene un espesor de placa sustancialmente mayor y una rigidez adicional significativa.The structural interleaved plate member shown in Figure 1 comprises upper outer plates and bottom (faceplates) 11, 12 that can be made of steel and that they have a thickness, for example, in the range of 0.5 to 20 mm. The edge plates are welded between the front plates 11, 12 around its outer peripheries to form a cavity closed. In the cavity between the front plates 11, 12 there is a core 13 of plastics or polymeric material, preferably a compact polyurethane elastomer (i.e. non-foamed). This core can have a thickness in the range of 15 to 200 mm; in the present request 160 mm is suitable. Core 13 joins the faceplates 11, 12 with sufficient strength and has mechanical properties sufficient to transfer the forces of Shears expected during use between the two faceplates. The bond strength between core 13 and face plates 11, 12 should be greater than 3 MPa, preferably 6 MPa and the module elasticity of the core material should be greater than 250 MPa. For low load applications, such as floor panels, where typical loads of use and occupation are of the order of 1.4 kPa at 7.2 kPa, the bond strength may be less, for example, approximately 1 MPa. Thanks to the core layer, the member of structural interleaved plates has the strength and ability to Loading support of a reinforced steel plate that has a substantially greater plate thickness and additional stiffness significant.
Para reducir el peso del miembro de placas intercaladas estructural 10, no todo el volumen entre las placas frontales 11, 12 está ocupado por el núcleo 13. En lugar de ello, se proporciona una serie de formas de peso ligero 14, que ocupan una parte sustancial del volumen interno del miembro de placa. Las formas de peso ligero 14 no necesitan contribuir significativamente a la resistencia estructural de la placa y requieren únicamente tener propiedades térmicas y mecánicas suficientes para soportar la presión de inyección del material para formar el núcleo 13, el calor de la reacción isotérmica del núcleo durante el curado y las temperaturas experimentadas durante las exposiciones a fuego.To reduce the weight of the plate member structural interleaved 10, not all the volume between the plates front 11, 12 is occupied by the core 13. Instead, it provides a number of lightweight forms 14, which occupy a substantial part of the internal volume of the plate member. The lightweight forms 14 need not contribute significantly to the structural strength of the plate and require only have sufficient thermal and mechanical properties to withstand the injection pressure of the material to form the core 13, the heat of the isothermal reaction of the core during curing and temperatures experienced during fire exposures.
Las formas 14 comprenden una tubería hueca 15 rellena con el material aislante resistente al fuego 16. La tubería 15 sirve para evitar que el material de núcleo líquido durante el moldeo por inyección del núcleo empape el material aislante, lo que asegura que no hay un hueco grande que se extiende a través del material de núcleo incluso durante condiciones de fuego reduciendo la conducción de calor entre las placas frontales 11, 12. La tubería 15, aunque se ilustra como de sección circular, puede tomar muchas otras formas, incluyendo secciones rectangular, hexagonal u octogonal y puede tener varillas internas para proporcionar resistencia adicional, o externas, para espaciar la forma lejos de otras formas, las placas de borde o las placas frontales. En general, la tubería puede tomar cualquiera de las formas descritas en la solicitud de patente internacional WO 02/078148. El material aislante es lana mineral, por ejemplo, como se suministra por Rockwool Limited of Pencoed, Bridgend CF35 6NY, UK. El material aislante puede tener una densidad en el intervalo de 30 kg/m^{3} a 200 kg/m^{3} y preferiblemente tiene un punto de ignición y un punto de fusión mayor de 1000ºC, preferiblemente.The shapes 14 comprise a hollow pipe 15 filled with fire-resistant insulating material 16. The pipe 15 serves to prevent the liquid core material during the Injection molding of the core soak the insulating material, which ensures that there is no large gap that extends through the core material even during fire conditions reducing heat conduction between the faceplates 11, 12. The pipe 15, although illustrated as circular in section, may take many other shapes, including rectangular, hexagonal or u sections octagonal and may have internal rods to provide additional resistance, or external, to space the way away from other shapes, edge plates or faceplates. In In general, the pipe can take any of the forms described in international patent application WO 02/078148. The material Insulator is mineral wool, for example, as supplied by Rockwool Limited of Pencoed, Bridgend CF35 6NY, UK. The material Insulator can have a density in the range of 30 kg / m3 at 200 kg / m 3 and preferably has a flash point and a melting point greater than 1000 ° C, preferably.
Para fabricar el miembro de placas intercaladas estructural 10, las placas de borde se sueldan alrededor de la periferia de la placa frontal inferior 11 y después las formas 14 y cualquiera de los espaciadores se colocan en la cavidad abierta resultante. En esta fase, cualquier sección premoldeada del núcleo puede ponerse en su sitio así como cualquiera de las placas de rotura u otras piezas de conexión que puedan desearse. Después, la placa frontal superior 12 se suelda a las placas de borde para formar una cavidad cerrada y los plásticos o el material polimérico se inyectan para formar el núcleo 13. Se permite entonces que el material inyectado se cure y los puertos de inyección usados en la etapa de inyección se cierran por rectificado y se sellan junto con los orificios de purga. Estas etapas pueden realizarse in situ o fuera del sitio, en condiciones de fábrica, y el panel acabado transportarse al sitio de instalación.To make the structural interleaved plate member 10, the edge plates are welded around the periphery of the lower front plate 11 and then the shapes 14 and any of the spacers are placed in the resulting open cavity. In this phase, any pre-molded section of the core can be put in place as well as any of the break plates or other connection pieces that may be desired. Then, the upper front plate 12 is welded to the edge plates to form a closed cavity and the plastics or the polymeric material are injected to form the core 13. The injected material is then allowed to cure and the injection ports used in The injection stage is closed by grinding and sealed together with the bleed holes. These steps can be carried out on site or off site, in factory conditions, and the finished panel transported to the installation site.
En la Figura 2 se muestra una segunda realización de la presente invención. El miembro de placas intercaladas estructuralmente de acuerdo con la segunda realización de la invención es similar a la primera realización pero difiere en la construcción de las formas de peso ligero como se describe a continuación.A second one is shown in Figure 2 embodiment of the present invention. The plate member structurally interspersed according to the second embodiment of the invention is similar to the first embodiment but differs in the construction of lightweight forms as described to continuation.
En la segunda realización, las formas de peso ligero 24 comprenden bloques 26 de material aislante que se forman con la forma deseada. Como se ilustra, los bloques son de sección cuadrada aunque pueden ser rectangulares, hexagonales, octogonales o tener una sección de otra forma y pueden tener una sección uniforme o variar en la sección transversal a lo largo de sus longitudes. Para evitar que el material de núcleo líquido empape el material aislante durante la inyección, los bloques 26 del primer material aislante resistente se pulverizan con o se sumergen en un material de recubrimiento que se endurece para proporcionar una capa externa impermeable (25).In the second embodiment, the weight forms lightweight 24 comprise blocks 26 of insulating material that are formed With the desired shape. As illustrated, the blocks are sectional square although they can be rectangular, hexagonal, octagonal or have a section in another way and they can have a section uniform or vary in cross section along their lengths To prevent the liquid core material from soaking the insulating material during injection, blocks 26 of the first resistant insulating material is sprayed with or immersed in a coating material that hardens to provide a layer waterproof outer (25).
La Figura 3 ilustra una tercera realización de la presente invención que difiere de la segunda realización en la manera de la formación de la barrera alrededor de los materiales aislantes. En la tercera realización, las formas de peso ligero 34 comprenden bloques 36 del material aislante resistente al fuego enrollado en un material laminar 35, en lugar de recubierto. El material laminar 35, por ejemplo, puede comprender una lámina metálica, fieltro, tela mineral o plásticos o lámina polimérica adecuados.Figure 3 illustrates a third embodiment of the present invention that differs from the second embodiment in the way of the formation of the barrier around the materials insulators In the third embodiment, the light weight forms 34 comprise blocks 36 of fire resistant insulating material rolled in a sheet material 35, instead of coated. He sheet material 35, for example, may comprise a sheet metal, felt, mineral or plastic cloth or polymer sheet adequate.
Se apreciará que la descripción anterior no pretende ser limitante y que se incluyen otras modificaciones y variaciones dentro del alcance de la presente invención, que se define mediante las reivindicaciones adjuntas. Por ejemplo, si el núcleo del miembro de placas intercaladas estructural se forma mediante bloques elastoméricos premoldeados, la barrera que encierra el material aislante resistente al fuego puede omitirse. También, cuando la forma de peso ligero se extiende entre las placas frontales del miembro de placas intercaladas estructural puede ser suficiente proporcionar una barrera únicamente sobre los lados de las formas de peso ligero que entrarán en contacto con el material de núcleo en lugar de encerrar totalmente las formas. Puede omitirse una barrera separada si el material aislante o al menos una región superficial de la forma es suficientemente densa como para que el acceso de material de núcleo líquido durante el moldeo esté limitado.It will be appreciated that the above description does not intended to be limiting and that other modifications are included and variations within the scope of the present invention, which are defined by the appended claims. For example, if the core of the structural intercalated plate member is formed using pre-molded elastomeric blocks, the barrier that encloses fire-resistant insulating material can be omitted. Also, when the lightweight form extends between the faceplates of the structural interleaved plate member it may be sufficient to provide a barrier only over sides of the lightweight forms that will come into contact with the core material instead of completely enclosing the forms. May omit a separate barrier if the insulating material or at least a surface region of the form is dense enough as so that the access of liquid core material during molding be limited
